Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other. Oil forms the upper layer while water forms lower. In separating funnel they are kept for resting, when two layers become stable by using separating funnel they are filtered one by one. The process involves using the mixtures of unequal particle density. The mechanism involves taking advantage of the unequal density of the particles in the mixture. Because water is denser than oil, it can be separated by means of the funnel and left in the funnel with an oil layer.
Method to separate
Once the liquids are taken in the funnel, we can see the formation of two layers. The denser liquid sinks to the bottom and the other liquid is on the top. A conical flask is placed at the bottom to collect the denser liquid. The valve allows you to control when and how of the liquid is let through down to the conical flask.
